Examples of the typical ETGs (left) and LTGs (right) with M _⋆  ≥ 10¹¹  M_⊙ in the COSMOS field. The postage stamps show a 30   h^-1 kpc  ×  30   h^-1 kpc area of the HST/ACS F814W image at the redshift of the source, with the North on the top and the East on the left. The pixel scale of the HST/ACS image is 0.05′′. The grey scale ranges from 0.5σ_sky to 150σ_sky, where σ_sky is the dispersion of the sky around the source. The redshift, the concentration (C) and the asymmetry (A) of the sources are labelled in the panels.
